B> Hello All:

B> I am facing a weird problem using a cisco 7206 with IP2IP GW. I have
B> been able to place calls from H323 to SIP and vice versa, but I am not
B> being able to complete any calls from SIP 2 SIP. It sometimes rings on
B> the other side, but the call is dropped before answering the phone,
B> and the other times it rings, we answer the phone, and the call is
B> dropped to the caller side, and I got error Interworking.

B> I tried dozen of codec configurations, also codec transparent, but it
B> does not work at all.

B> Does any body has any idea what might be happening ?

B> Please.. see below my main config file and some debugs..

B> Many thanks.
